Watch: See how to correctly mix Micro, Grow, and Bloom using the Cronk 3-Part Base system.
The Core Components: Micro, Grow, and Bloom
Micro — The Foundation
Micro provides essential trace minerals and stabilizes your nutrient mix.
It supports strong plant structure and helps regulate nutrient uptake across every stage of growth.
Grow — Power for Vegetative Growth
Grow fuels lush, vigorous leaves and stems during the vegetative phase.
It’s rich in nitrogen, helping plants develop thick canopies and robust roots.
Bloom — Strength for Flowering
Bloom provides phosphorus and potassium to boost flower size, density, and flavor.
It ensures abundant blooms and supports high-yield, nutrient-dense results.
⚖️ Mixing Made Simple: Step-by-Step
Step 1: Choose Your Feed Chart
Start by selecting the correct Cronk Nutrients 3-Part Feed Chart for your growing setup — soil, coco, or hydro. Each chart is tailored for your experience level and growth stage.
Step 2: Example Mix — Week 3 (Vegetative Stage)
Here’s an example using Week 3 of the Beginner 3-Part Feed Chart for a 5-gallon batch:
| Product | mL per Gallon | Total for 5 Gallons |
|---|---|---|
| Micro | 4 mL | 20 mL |
| Grow | 3 mL | 15 mL |
| Bloom | 1 mL | 5 mL |
🧪 Mixing Order Matters:
1️⃣ Add Micro first and stir thoroughly.
2️⃣ Add Grow, mix well.
3️⃣ Add Bloom last and stir until completely blended.
💡 Pro Tip: Never mix nutrients directly together in their concentrated form — always dilute each one in water before adding the next.
Step 3: Check and Adjust pH
After mixing, test your nutrient solution with a reliable pH meter.
Coco or Hydro: pH 5.6–5.8
Soil: pH 6.0–6.3
Correct pH allows plants to absorb nutrients efficiently and prevents lockout.

Step 4: Watering Best Practices
For Seedlings:
Keep soil moist but not soaked. Overwatering early can damage roots.
For Mature Plants:
As plants grow, water until you reach around 20% runoff to prevent salt buildup and ensure even nutrient distribution.
Pro Tip: Rotate feedings, water once with nutrients the next without.
🌿 Key Takeaways
✅ Always mix in this order: Micro → Grow → Bloom
✅ Never combine nutrients in concentrated form
✅ Adjust pH every time you feed
✅ Follow your feed chart exactly — don’t eyeball measurements
✅ Alternate between nutrient and plain water feedings
✅ Store mixed solution up to 7–10 days, stirring before each use
